ABCKristin Cavallari practices with Mark Ballas in 2011 for "Dancing with the Stars." According to the Food Network, on Sunday, when the Sweet Spot Bake Shoppe's Cheryl Burger is scheduled to be on "Cupcake Wars," she'll be vying to serve treats at Cavallari's baby shower.

At least, it is for Cheryl Burger, owner of the Sweet Spot Bake Shoppe in Chester Township. She'll be appearing Sunday at 8 p.m. on the Food Network's "Cupcake Wars."

For months, Burger couldn't say anything about her appearance on the show, which she taped in Los Angeles in March. Agreements with the show barred it. Instead, she told customers she was visiting her grandmother — an unwitting accomplice to a little white lie.

But last week, she began letting them know: tune in Sunday to see your favorite cupcake shop on national television.

"It's completely overwhelming, the outpouring of support that we've gotten from out customers," Burger said. "Now we can tell them we're on the show, but unfortunately, we can't say anything else about what will happen."

Burger said her friends and employees have been urging her to audition since she started the Sweet Bake Shoppe in 2010, with her sister.

"We kept hearing more and more from the girls who work here. I must have caved, she said.

"Cupcake Wars" pits four cupcake-making contestants against each other for three rounds of elimination. It asks contestants to make cupcakes at a rapid pace, with judging in the early rounds based on creativity with a theme, then taste and presentation. In the last round, the final two teams (with a little help from some baking interns and a carpenter) has to make 1,000 cupcakes in just two hours, then showcase them.

That's a bit more hectic than the average day at the Sweet Bake Shop. Burger said part of what sets her shop apart — and part of what she hoped to impress upon the judges — is that she always makes her cupcakes from scratch. That means she sacrifices some of the efficiencies associated with pre-made mixes. She makes just two dozen cupcakes at a time.

"It's basically how many you could make if you were doing it in your own home," Burger said.

According to the Food Network, in Sunday's episode, competitors will be vying to serve their treats at television star Kristin Cavallari's baby shower.

Burger first made her written application in January, then did a phone interview, and then a video application. It's the last part that was the most intimidating.

"I definitely freeze up a bit in front of the camera," she said.

And that, of course, is exactly what TV producers don't want to see. During her phone interview, Burger said, she was encouraged to really let her personality shine — even if she felt silly or dramatic.

"I was getting tense, in the application video," she said. "So at point point, I said, 'OK, enough. I'm trying to do the super-sweet cupcake baker thing, but this isn't me. I'm a baker. I'm here to win. This is what I'm here to do.'"

Burger's pretty sure that's what caught the producers' attention. Though she can't say how she fared in the competition, Burger said she thinks she acquitted herself, and her bake shop, well.

Burger and friends will be gathering for a private party in Flanders to watch the show. Then, she expects to open the shop at 11 a.m. Monday — when it's normally closed — and stay open until 6 p.m., or until she runs out of cupcakes, whichever comes first. An earlier version of this post incorrectly said the shop would be open from 6 a.m. to 11 p.m.

"I get e-mails from our customers. They loved us long before this was going on, but they've shown us so much more support," she said. "I have to be excited about the fact that this will draw a lot of attention to the shop, a lot of attention to Chester. It's a great thing."
